Micronutrient malnutrition is a serious public health problem in developing countries, including Sri Lanka. Most frequently, micronutrient malnutrition is experienced by the poorest households due to cereal-based, monotonous diets that lack dietary diversity. Sri Lankan traditional food system is changing day by day. In parallel, nutrition deficiencies, malnutrition, and noncommunicable diseases are the most significant problems today in Sri Lanka. Therefore, understanding dietary diversity and dietary changes in Sri Lanka must be studied to address related public health issues. This study investigates nutrition adequacy, dietary diversity, dietary practice, and traditional food pattern changes in different marginalised areas in Sri Lanka. A cross-sectional survey was done using 24 h food recall and an administrative questionnaire for 400 women of reproductive age (WRA) (18–49 years old) in marginalised areas in Sri Lanka. The random sampling method was used for data collection. The research confirmed that different areas had poor dietary practices, with macronutrient imbalance and alarmingly low intakes of micronutrients. Interestingly, the diversity of food was higher in rural areas than in urban areas. Approximately 83% of women in urban areas did not meet minimum dietary diversity (MDD-W). Overall, about 63% of reproductive age women did not meet MDD-W and food security. The mean MDD-W for both areas was low. Significant differences in MDD-W levels were found in the two areas (F = 90.483, p < 0.05). The sample showed a significant positive correlation between MDD-W and area, monthly income, educational level, food source, BMI level and health status (R² = 360; p < 0.01). This sample did not find that the consumption of traditional varieties of foods and agrobiodiversity are decreasing. Additionally, the study confirmed that low dietary diversity impacts nutrition status and health. The results highlight that the leading causes for low diet diversity are decreased dependence on own production, increased purchasing food at markets, lack of suitable lands to cultivate, agro-commercialisation, less knowledge of food and nutrition, loss of traditional food culture, low income and high prices of food. Inappropriate food patterns, nutrition policies and governance in Sri Lanka are the main factors to the nutrition findings. The study finding will help the decision-making authorities or policymakers to design suitable nutrition programs for vulnerable people in marginalised areas and to use these to strengthen a sustainable food and nutrition system in Sri Lanka.

Nutrient deficiencies are a public health problem in Sri Lanka. Achieving food security is a major challenge due to unhealthy eating patterns. The nutritional status of a woman and her knowledge is a powerful indicator of the nutritional security of her children and household food security. Nutrition-related knowledge and attitude are necessary for dietary changes towards a healthier dietary pattern. For that reason, food and nutrition-related Knowledge, Attitude and Practice (KAP) is one of the key factors to achieving household food and nutritional security. The main objective of this study is to assess the food and nutrition-related KAP among reproductive-age women and understanding of household food and nutritional security in Sri Lanka as an example for marginalized societies. Thus, a cross-sectional survey was conducted using the KAP model questionnaire administered on 400 reproductive age women (18–49 Years) in marginalized areas in Sri Lanka. Data were collected using a random sampling method. The research results clearly showed that the reproductive age women have a low level of nutritional knowledge in the areas being investigated. Most women have a positive attitude towards receiving nutritional knowledge but have low-level practice about a healthy diet. Furthermore, knowledge, practices, and attitudes of women largely affect their BMI status, as well as household food security. Multiple linear regression analysis was used to analyze the influential factors. There was a highly significant positive correlation between nutritional knowledge, attitude score, and BMI level and a significant difference was found in the area, age, family size, monthly income, educational level, attitudes towards nutrition, food and nutrition practices across the reproductive women (R²: 467, p < 0.01). The research results showed that KAP largely determines women’s nutrition and household food security. Based on the results of this research, there is a need to enhance nutritional education in reproductive-age women in marginalized areas in Sri Lanka.

Sri Lanka was a colony of the Portuguese, Dutch, and British. The simplification of Sri Lankan food culture can be seen most clearly today, including how the diet has been changed in the last 400 years since the colonial occupation began. Therefore, greater efforts must be made to uncover the colonial forces that have undermined food security and health in Sri Lanka. Also traditional eating habits, which are associated with countless health benefits, have been gradually replaced by the globalized food system of multinational corporations and hidden hunger, a system inherent in the emergence of non-communicable diseases, such as cancer, diabetes, cholesterol, and kidney disease epidemics, in Sri Lanka. This article discusses factors that have underpinned the dietary change in Sri Lanka from its early colonization to the post-colonization period. The research followed the integrated concept in ethnological and sociological study approaches. The study examined literature and conducted several interviews with field experts and senior people in marginal areas in Sri Lanka. This study examines the Sri Lankan traditional food system and how it changed after the colonial period, including the main changes and their impact on current micronutrient deficiencies and non-communicable diseases.

Increasing health threats is a common problem among both rice growers and consumers in many parts of Sri Lanka and in the Asian region in general. Increasing trends in growing and consuming traditional rice could be observed in searching solutions for these problems. This study explored objectively the factors affecting willingness to grow traditional rice and its varietal selection in Anuradhapura district of Sri Lanka. 100 traditional and 100 non-traditional rice growers were selected using stratified sampling method for the field survey and data were analyzed descriptively, using logistic regression and factor analysis. Results revealed that 67% of the male farmers were willing to cultivate traditional rice over improved varieties and 65.6% traditional rice cultivation was observed among families with non-communicable diseases. Awareness of medicinal and nutritional values of traditional rice, land extent, farm gate price, age and education level of farmers, farming experience and farming system significantly affects (P ≤ 0.05) the willingness to cultivate traditional rice while factors related to varietal attributes, personal, market and production, respectively affects selection of traditional rice variety. Results conclude that farmers are willing to cultivate traditional rice in Anuradhapura district of Sri Lanka and selection of traditional rice varieties is most affected by varietal attributes which are adoptable to existing environmental conditions and personal factors like presence of non-communicable diseases, age of the farmers, education level and experience for farming.
